How can I schedule tasks in Flask using Celery?

You can schedule tasks in Flask using Celery by setting up a Celery instance and defining periodic tasks with the help of the Celery beat scheduler.

What do I need to install to get started with Flask and Celery?

You'll need to install Flask, Celery, and a message broker like Redis or RabbitMQ. You can do this using pip.

Can you show me a simple example of a scheduled task?

Sure! Here's a basic example:

from celery import Celery

app = Celery('tasks', broker='redis://localhost:6379/0')

@app.task
def add(x, y):
    return x + y

app.conf.beat_schedule = {
    'add-every-30-seconds': {
        'task': 'tasks.add',
        'schedule': 30.0,
        'args': (16, 16),
    },
}
